My decision to use iHerb was a good one. I found the product that I wanted at the lowest price compared to the other sites I usually purchase from. And shipping was unbelievable. My item was at my door before the transaction even registered on my bank account! No joke! AS far as product quality, I've just started using it, but have experienced better digestion and stomach ease through the week. I am also taking protein supplements so I'm sure my digestive tract will benefit and be more efficient in getting me the nutrients I need. I HIGHLY recommend iHerb for the product you're looking for and am glad that I had this opportunity give my review. Thank You.

I have IBS problems and the bacillus coagulans works pretty well and doesn't need refrigeration. Ive switched to DuraFlora, I think its a better deal/price but same strain. I can tell when a probiotic is working because if it doesn't I suffer with insomnia...

I have been taking the probiotic ,Sustenex, for about six months and it has had a positive impact on my digestive health.I also feel it has strengthened my immune system. I am switching to this Twinlab product, as it is the identical probiotic and strength as Sustenex at a more economical price. So far it seems to have the same effect on my system.
